Friday September 5, 2014 Smoke Impact Summary - Klamath NF

Yesterday Winds
pushed smoke to the Southwest which impacted the communities of the lower
Klamath, Salmon, and Trinity River drainages.
Dispersion was good and kept most of the smoke aloft and from settling
into drainages.

Today
Smoke is predicted to travel southwest down the Klamath and Salmon River
drainages in the morning hours. By
afternoon, smoke will change directions and head eastward to the Scott and
Shasta Valley. Smoke concentrations
are forecast to be more localized as dispersion is predicted to be low. This means that communities surrounding the
active fires will be impacted by smoke until the weather changes.

Tomorrow Weather
will be similar to the previous day. Smoke
is forecast to pool into valleys and drainages with low dispersion. Communities to the west of the fires may
experience improved conditions as an onshore flow pushes the smoke slightly
westward.
